Last question: do all peltiers then ,with the mark sr, fall under your brand? thank you.

No, not at all. It is very likely you will find other peltier chips with various performance characteristics that will also say SR on it. Do not use this as a way of determining chip quality or performance. There are several easy ways to test the true amp draw of these chips using a battery and a multimeter, you can contact us for more detailed help. Many 12706 and 12715's on the market are under-powered because the thermoelectic material is very expensive and it's a fast way to reduce chip cost, is to use less thermoelectric material. Only by testing can you be sure of what you are getting.

What does SR mean under the model number? Thank you.

Hello, it's just an internal manufacturing code.

What is the outside material of these made of (The white part)?

Ceramic (Al2O3 - Alumina or aluminum oxide).

What are the product (chip) dimensions, HxWxD ?

1.5 inches but very close to 1 and 9/16 x 1and 5/8 I took this without my glass's on when I did my project, I went with 1.5 x1.5 inches. I hope that helps.

First time replacing one of these. Was very easy and a perfect replacement for the stock cooler. Cooled wine cooler faster than original. Watched a you tube video to make sure installed in right direction. I believe it was label side is the cold side.
